I haven't read the full thread yet, but I'll add my thoughts.
I pirate. I think it's okay or at least understandable within certain situations.
1. I always pirate something if it's not available in my country and I want to have it. I know it's not always the creators' fault, but if this is the reason for pirating, I always donate the price of the creation.
2. For software, if I bought it but from a different OS and the keys are non-exchangeable, I always pirate it. First, I check if it will work on the new OS. If not, I ask for an exchange. If not, I pirate it. I may even sell the old license key to some other guy. The creators didn't bother to give me a new key or make the key multiplatform and I paid for it, so why shouldn't I sell my old key as well? I know that may seem OTT to some, but I think it's fair.
I also pirate music, movies, software, etc. all the time for no reason than, "I want to". I never listened to music or watched movies on Windows. I didn't even buy software, though I downloaded and pirated them.
When I moved to OS X, I started going on a pirate frenzy, since I needed software to fill up my Mac and the free ones weren't usually as good as the paid ones.
I don't do this anymore. I may pirate, but whenever I earn money, the first thing I do is pay my debts, and I do believe I owe a debt to the creators of the software I pirated. I don't pay for the movies for some reason, unless it's on iTunes. If the music is on iTunes, I will also pay for it. If the software is not on the MAS, I still pay for it but would be more likely to pay for the ones on the store first.
If it's easy to pay the creators and I earn the money, I will pay as much as I can to them.
